Further research
has lead me to think that when Dad was assigned to HMS Cochrane in October 1942
from the Nelson, whilst alongside in Rosyth, it was not for training or a shore
base but a depot ship that was alongside permanently. It seems the HMS Cochrane
I was the shore base and HMS Cochrane II was the accounting posting for spare
bods. HMS Cochrane was designated as a Base depot ship, or sometimes know as a
destroyer depot ship. She started out as the Booth Line passenger ship RMS
Ambrose. She was built on the Tyne and delivered in October 1903. Her
employment was from Liverpool to South America and especially the Amazon and
Manaus. She was built for the rubber boom and carried 149 1st Class
and 330 steerage Class. She was 375’ x 48’ x 18’ draft. 4588grt and 2490 nrt
and did 12 kts. An interesting story occurred in 1913 in the Mersey shipping
channel off Hoylake. A council dump hopper barge BETA had just dumped her cargo
of refuse when she collided with a fishing boat called FLEETWING. Beta was just
rescuing 4 men from the water when the RMS Ambrose ran into her stern when
inbound to Liverpool. If it wasn’t odd enough that there were two collisions
like that, one of the twelve who lost their lives was an AB called A. Porter!
She was
requisitioned in December 1914 by the Navy and converted into an armed merchant
cruiser becoming AMC Ambrose. She joined the 10th Cruiser Squadron
whose task it was to guard the northern approaches from the Norwegian coast
right out into the Atlantic. She was again converted to a submarine depot ship
in 1915. Her Grt increased to 6600t and
her compliment was 238. In 1917 she was in Malta and in 1919 she was in
Portsmouth. Then in 1927 she was in China as the depot ship for the 4th
Submarine Flotilla when the submarine Poseidon was sunk in collision with a
Chinese ship and 4 men escaped using escape breathing equipment for the first
time. Some sources then say she was later converted again into a depot ship for
destroyers. 1932 found her on the reserve list and in 1936 she was not even on
that list. She was obviously reprieved and in 1938 she had her name changed to
HMS Cochrane and appears to have been the base depot ship at Rosyth throughout
the war. She was scrapped in 1946.
